About us

Integrated Services with People at the Heart

At WessexME, we deliver fully integrated mechanical, electrical, and energy services that help organisations keep their buildings safe, compliant, and performing at their best. This includes complex installations, technical compliance, planned maintenance, and specialist engineering support. 

We provide the expertise and reliability needed to ensure building systems run efficiently. 

Valued by for our expertise and reliability, we offer a genuine partnership for facilities management teams and end clients across a wide range of sectors. Our clients trust us because we bring dependable, straightforward guidance - and a team that genuinely cares about getting the job done right. 

A Heritage of Proven Expertise

WessexME was created in 2025 through the merger of three respected industry specialists: Wessex Electricals, Watertite Building Services, and Spectrum Electrical. Each company brought a long history of technical skill, trusted relationships, and sector expertise. By bringing the three companies together to form a unified team, WessexME can deliver even greater capability and reach, whilst maintaining the personal, people-focused approach that defined them.

Wessex Electricals, originally part of the Wessex Group founded in 1963, became part of the andwis Group in 2024 before joining forces with Watertite and Spectrum to help form WessexME.

Watertite was founded in 1987 and incorporated into the andwis Group in 2023, bringing extensive mechanical, plumbing, and heating knowledge.

Spectrum added further strength in commercial and industrial electrical solutions.

Elliott Environmental bring many years of expertise in designing and delivering high quality, cost effective and reliable air conditioning, ventilation, and heating solutions.

By combining these complementary disciplines, WessexME now delivers fully integrated mechanical, electrical, and energy services under one name.

Partnership for Progress

The culture of WessexME has been built around people – our teams, our clients, and the communities we serve. As our company evolves, we continue to deliver the trusted, personal approach that has shaped our reputation for generations.

We are proud to maintain long-standing relationships that span decades: from 50 years supporting Wiltshire Council to more than 10 years partnering with the Aster Group. These partnerships are built on consistency, transparency, and the belief that the best results come from working side by side.

Just as important is the positive impact we make beyond our projects. Our teams are actively involved in delivering social value across our communities - from donating refurbished laptops, supporting residents’ access to work and learning opportunities, to installing memorial benches and planting trees that enhance community spaces. We believe in creating meaningful, lasting difference beyond the services we provide.

Growing the Next Generation

Our commitment to people extends across our entire workforce. We invest heavily in apprenticeships, training, and long-term development - ensuring a strong pipeline of future engineers, supervisors, and office professionals. Many of our team members have built decades-long careers with us, creating a culture of stability, loyalty, and expertise that benefits every project we deliver. 

Giving Back to the Communities we Serve

Supporting our communities also means supporting the causes that matter to them. Each year, our teams take part in a wide range of fundraising initiatives - from charity cycle challenges for organisations such as The Friends of Wincanton Community Hospital, to bake sales, competitions, and staff-led campaigns. As part of the wider Wessex Group, our people have helped raise thousands of pounds for charities including Marie Curie, Red Nose Day, and a number of local mental health and cancer support organisations.

These efforts reflect not only our social responsibility, but the generosity and enthusiasm of the people who make up WessexME.
